Astronomers have discovered a potential “rogue” alien planet wandering alone just 100 light-years from Earth, suggesting that such starless worlds may be extremely common across the galaxy.

The free-floating object, called CFBDSIR2149, is likely a gas giant planet four to seven times more massive than Jupiter, scientists say in a new study unveiled today (Nov. 14). The planet cruises unbound through space relatively close to Earth (in astronomical terms), perhaps after being booted from its own solar system.

Someone probably hijacked it and is joyriding it across the galaxy.

Apparently, starless planets are news only to me.

The discovery of a starless alien planet would not be shocking, at least not anymore. In the last year or so, astronomers have spotted a number of such orphan worlds — so many, in fact, that some scientists think parentless planets are the rule rather than the exception.

One 2011 study, for example, estimated that rogue worlds outnumber “normal” planets with obvious host stars by at least 50 percent throughout the Milky Way. If that’s the case, the galaxy that includes Earth probably also hosts billions of orphan planets.

And gas giants may be in the minority among these solitary wanderers, researchers say.

“We now know that such massive planets are rare and that Neptunes or Earth-mass planets are much more common,” Delorme said. “We also know that massive objects are more difficult to eject [from solar systems] than light ones. If you follow the rationale, you deduce that ejected exo-Neptunes and ejected exo-Earths should be much more common than objects like CFBDSIR2149.”

I really wish I could look at the universe through the eyes (and mind) of people like Sean Carroll, or at life through the eyes of PZ Myers. How staggeringly more beautiful it must be to them.
